Mexican state of Chihuahua (Chihuahua), mine Naik (Naica Mine), Crystal Cave (Cueva de Los Cristales). At a depth of 300 meters detected cavity housing a giant selenistokislye crystals, some of the largest natural crystals ever found. The crystals were formed by hydrothermal fluids emanating from the bottom of faults. The cave was discovered by accident, miners forced to drill a hole, because Nike's management was concerned about the probability of flooding fields.
